pub struct PanesRenderState {
pub tree: Arc<PaneTree>,
}Expand description
Pane tree’s render-side projection.
Phase 5.8.AF.5 / Slice 3c.final.B (group 1): populated.
Carries a clone of the editor’s [PaneTree] inside an Arc
so subsequent reader frames share the same allocation.
Renderers read rs.panes.tree.X() instead of
app.editor.pane_tree.X(); every existing PaneTree method
(root, leaves, active, active_index, compute_rects)
flows through unchanged.
Arc::new(self.pane_tree.clone()) on publish is the simple
shape; the PaneTree::clone cost is bounded by the tree depth
(one Vec<PaneState> + a handful of Box<PaneNode> allocations
for splits). For typical 1–3 pane layouts this is sub-µs.
Optimisation path (post-1.0): keep an Arc<PaneTree> on the
editor side and Arc::make_mut on mutation so publish collapses
to one Arc bump.
